Dear sweety, the correction window for editing your application form has been closed long back. Now the next step is downloading the admit card when it is released tentatively on April 15th. Now its too late to expect any changes to be allowed in your application. However, if it is just title that has been entered wrong, leave it that way because eitherways it doesnt effect your merit. If its a mistake in your name, once the results have been announced you can get an affidavit done.
